Scientists at Rosatom have completed the development of a prototype plasma electric motor based on a magnetic accelerator. The technology operates in pulsed-periodic mode and reaches an average power of 300 kilowatts. Especialistas indicate that the system could shorten the land journey to Marte of months to 30 to 60 days.
The thrust generated reaches around 6 newtons. Partículas accelerated ones reach speeds of up to 100 kilometers per second. Esses parameters significantly outperform traditional chemical engines used in current missions.
The drastic reduction in travel time reduces astronauts’ exposure to cosmic radiation. The advance is part of the Russian national program launched in 2025 for leadership in space nuclear technologies.
Technical characteristics of the prototype
The engine uses magnetically accelerated hydrogen plasma. The design allows continuous operation for extended periods without excessive component wear.
Initial tests confirmed higher energy efficiency than conventional systems. The average power of 300 kW sustains constant acceleration in a deep space environment.
Benefits for manned missions
Decreasing travel time solves one of the biggest obstacles to human exploration of Marte. Viagens currently require around six to nine months on the way there, increasing health risks.
With the new engine, round-trip missions become logistically viable. Astronautas face less exposure to galactic radiation, which can cause severe cellular damage.
Furthermore, the technology facilitates the transport of larger loads. Naves equipped with plasma propulsion require less chemical fuel for terrestrial escape.
Tests under simulated conditions
Rosatom sets up large-scale experimental structure on Troitsk. The installation includes a vacuum chamber 14 meters long and 4 meters in diameter.
These tests reproduce the emptiness of deep space. Engenheiros evaluate the prototype’s continuous performance and measure real thrust parameters.
Results will determine necessary adjustments before integration into spacecraft. The current phase focuses on validating the system’s durability for thousands of hours.
Comparison with current propulsion
Chemical engines offer high initial thrust but low long-term efficiency. Eles depend on explosive reactions that consume large amounts of propellant.
Traditional ionic systems accelerate ions to high speeds, but generate very low thrust. Isso limits application to large-mass manned ships.
- Exhaust speed: up to 100 km/s on the Russian prototype
- Thrust: 6 newtons sustained
- Power: 300 kW average in pulsed mode
- Comparison: chemical engines reach around 4.5 km/s

Agencies like NASA and ESA have been investing in advanced propulsion for decades. The American VASIMR project aims for similar times, but is still in the experimental phase.
The China advances nuclear thermal engines for missions to the red planet. Parcerias international organizations discuss common standards for safety in manned flights.
Rússia maintains a tradition in space nuclear technologies since the Soviet era. Previous Projetos have included nuclear tugs for high orbits.
Implications for future exploration
The success of the prototype paves the way for nuclear-electric tugs. Essas ships would transport habitation modules and heavy equipment between planets.
Scientists estimate that average speeds of 314 thousand km/h make interplanetary journeys routine. The technology also benefits missions to asteroids and moons of Júpiter.
Experts highlight the need for additional protection against radiation even on short trips. Escudos complementary magnets are being studied in parallel.
Advances in radiological safety
Cosmic radiation represents a major risk on long space journeys. High-energy Partículas penetrates conventional armor and damages human DNA.
Trips reduced to weeks minimize accumulation of lethal doses. Estudos indicate a drop of up to 80% in total exposure compared to traditional missions.
- Reduction of long-term oncological risks
- Lower incidence of acute radiation syndrome
